Spring MVC 설정

Maven Project 생성

File - New - Maven Project - Archetype 선택(Group Id : org.apache.maven.archetypes, Artifact Id : maven-archetype-webapp) - Group Id, Artifact Id 입력 - finish

 

폴더 추가

Maven Project를 최초 생성하면 위와 같은 구조를 가지고 있는데 Maven Project 디렉토리 구조를 만들기 위해서 아래와 같이 main 폴더 하위에 java, resources 폴더를 생성한다.

ㄴsrc
    ㄴmain
        ㄴjava : 자바 패키지 폴더와 소스 코드가 위치함.
        ㄴresources : *.properties, *.xml 등 설정파일들이 위치함.
        ㄴwebapp : WEB-INF와 웹 관련 리소스(html, jsp)들이 위치함.
    ㄴtest
        ㄴjava : 테스트와 관련된 자바 패키지와 소스코드가 위치함.
        ㄴresources : 테스트와 관련된 설정파일이 위치함.
ㄴtarget : 컴파일, 패키징된 결과물이 위치함.
ㄴpom.xml : Maven 설정 파일

 

 

1. pom.xml 수정

pom.xml 파일을 아래와 같이 수정 후 프로젝트 우클릭 -> Maven -> Update Project

<properties>
  <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  <maven.compiler.source>1.8</maven.compiler.source>
  <maven.compiler.target>1.8</maven.compiler.target>
  <spring.version>4.3.5.RELEASE</spring.version>
</properties>

<dependencies>

  <!-- Spring -->
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context</artifactId>
    <version>${spring.version}</version>
  </dependency>
  <dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>${spring.version}</version>
  </dependency>


  <!-- Servlet JSP JSTL -->
  <dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>javax.servlet-api</artifactId>
    <version>3.1.0</version>
    <scope>provided</scope>
  </dependency>

  <dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>javax.servlet.jsp-api</artifactId>
    <version>2.3.1</version>
    <scope>provided</scope>
  </dependency>

  <dependency>
    <groupId>jstl</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
  </dependency>

</dependencies>

 

2. org.eclipse.wst.common.project.facet.core.xml 수정

이클립스 Navigator에서 .settings 하위 org.eclipse.wst.common.project.facet.core.xml을 열어서 버전을 고친다.

저장 후 이클립스 재시작

<?xml version="1.0" encoding="UTF-8"?>
<faceted-project>
<fixed facet="wst.jsdt.web"/>
<installed facet="jst.web" version="3.1"/><!-- servlet 버전 2.5 -> 3.1 -->
<installed facet="wst.jsdt.web" version="1.0"/>
<installed facet="java" version="1.8"/>
</faceted-project>

 

3. src/main/java 폴더 생성 -> 패키지 생성(kr.or.connect.mvcexam.config) -> WebMvcContextConfiguration.java 작성(=DispatcherServlet 설정)

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = { "kr.or.connect.mvcexam.controller" })
public class WebMvcContextConfiguration extends WebMvcConfigurerAdapter {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/assets/**").addResourceLocations("classpath:/META-INF/resources/webjars/").setCachePeriod(31556926);
        registry.addResourceHandler("/css/**").addResourceLocations("/css/").setCachePeriod(31556926);
        registry.addResourceHandler("/img/**").addResourceLocations("/img/").setCachePeriod(31556926);
        registry.addResourceHandler("/js/**").addResourceLocations("/js/").setCachePeriod(31556926);
    }

    // default servlet handler를 사용하게 합니다.
    @Override
    public void configureDefaultServletHandling(DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Override
    public void addViewControllers(final ViewControllerRegistry registry) {
        System.out.println("addViewControllers가 호출됩니다. ");
        registry.addViewController("/").setViewName("main");
    }

    @Bean
    public InternalResourceViewResolver getInternalResourceViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/views/");
        resolver.setSuffix(".jsp");
        return resolver;
    }
}

 

4. web.xml 수정

WebMvcContextConfiguration의 경로를 지정한다.

<?xml version="1.0" encoding="UTF-8"?>
<!-- Servlet 3.1 이상에서 설정 -->
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd"
version="3.1">
  <display-name>Archetype Created Web Application</display-name>
  
  <context-param>
    <param-name>contextClass</param-name>
    <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
  </context-param>
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>kr.or.connect.mvcexam.config.ApplicationConfig</param-value>
  </context-param>
  <!-- ContextLoaderListener가 실행될 때 위 context-param을 참조한다. -->
  <!-- Context Load(서버 Load)할 때 DBConfig과 ApplicationConfig을 읽는다. -->
  <listener>
  	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  
  <servlet>
    <servlet-name>mvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextClass</param-name>
      <param-value>org.springframework.web.context.support.AnnotationConfigWebApplicationContext</param-value>
    </init-param>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>kr.or.connect.mvcexam.config.WebMvcContextConfiguration</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>mvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

 

5. 테스트

src/main/webapp/WEB-INF/views/main.jsp 생성 후 Run
